Shannon and pielou indices
WebbShannon–Weiner index or Simpson index was mostly used. Other indices such as Log series, Margalef index, McIntosh index, and Berger–Parker index were seldom used in describing forest community attributes with species diversity indices.

WebbThe analysis of plant diversity showed that the richness index of the tree layer was 4–18, the Simpson index was concentrated in the range of 0.65–0.9, the Shannon–Wiener index was 1.32–2.30, and the Pielou and Alatalo indexes were concentrated at 0.7–0.95 and 0.6–0.9, respectively , which were basically consistent with the species diversity of the … Webb4 mars 2024 · The indices of Sobs, Shannon, and Pielou represented the AMF community richness, diversity, and evenness, respectively. When based on the species level, the highest species richness occurred at the elevations of 1,800 and 2,200 m ( Figure 2A ). The highest Shannon diversity and Pielou evenness both appeared at 1,170 m ( Figures 2B,C ).
